ruby-on-rails - Rails image_tag 旋转图像

Question

我正在使用亚马逊的 S3 进行图像存储，并配置了载波和雾。这些图像似乎可以正确存储，但是当我有一个“肖像”图像(宽度小于高度)时，它没有正确显示，而是在其侧面旋转图像。

任何指向正确方向的指示都将不胜感激!

上传者/image_uploader.rb

class ImageUploader < CarrierWave::Uploader::Base
  include CarrierWave::RMagick

  include Sprockets::Helpers::RailsHelper
  include Sprockets::Helpers::IsolatedHelper

  storage :fog

  include CarrierWave::MimeTypes
  process :set_content_type

  process :resize_to_limit => [420, 0]

  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  def extension_white_list
    %w(jpg jpeg png)
  end

end

显示.html.haml

= image_tag(@idea.image_attachments.first.image.url).to_s

图片附件.rb

class ImageAttachment < ActiveRecord::Base
  require 'carrierwave/orm/activerecord'
  attr_accessible :image, :description
  belongs_to :image_attachable, polymorphic: true
  mount_uploader :image, ImageUploader
end

Answer 1

在uploader.rb文件中，尝试

process :auto_orient 

def auto_orient
 manipulate! do |image|
   image.tap(&:auto_orient)
 end
end

它应该修复它。
